  abstract = {{I}n atoll lagoons, plankton richness is highly dependent on water exchange with the ocean through the atoll rim. {H}owever, the dynamics of the physical and biological fluxes at the lagoon-ocean interface remain poorly characterized. {H}ere, we studied the combined effects of lagoon-ocean water exchanges and local environmental conditions on the phyto- and zooplankton abundance and community structure across the atoll lagoon rim of {A}he ({T}uamotu {A}rchipelago, {F}rench {P}olynesia). {P}lankton and environmental variables were monitored in {M}ay 2013 (i) at several stations inside and outside the lagoon and (ii) during time-series corresponding to ebb-flood tidal cycles in the two types of channels connecting the lagoon to the ocean: at the passage (300 m long and about 11 m deep) and in hoa (i.e reef-flat less than 50 cm depth). {O}ur results highlight tidally-driven selective plankton exchanges between the lagoon and external ocean. {P}hytoplankton (chlorophyll-a) and zooplankton biomass were respectively 4 times and 7 times higher in the lagoon than at stations outside the atoll lagoon. {C}opepoda was the dominant zooplanlcton group at the oceanic station (>75% abundance) whereas meroplankton (with bivalve larvae most common) was dominant at the lagoon stations (54%), in the passage (55-82%) and in hoa (>80%). {T}hese differences between sites suggest a loss of bivalve larvae through export to the ocean and retention and/or increased production of copepods in the lagoon. {T}he daily export of bivalve larvae represents a low percentage of the lagoon stock, in agreement with previously published larval dispersal numerical models. {T}he retention of copepods could constitute a significant input of nutrients and organic matter (through excretion, feces release, decomposition, and remineralization) into the lagoon.},
